Which coin is likely to come up, if a coin is drawn at random from a box containing coins as shown in the table?
 Coin Number of coins Dimes 10 Nickels 7 Quarters 4 Pennies 2
 a. Dime b. Penny c. Quarter d. Nickel

#### Solution:

Since dimes are more in number than any other coins, the probability that a dime will be drawn is more.

So, it is more likely that the coin drawn will be a dime.

12.
A ball is picked at random from a box containing balls of different colors. Which color ball is more likely to be picked out of the box?
 Color Probability white $\frac{9}{17}$ brown $\frac{4}{17}$ green $\frac{4}{17}$
 a. white ball b. green ball c. all the colors d. brown ball

#### Solution:

The probability of picking a white ball is more than the probability of picking any other ball.

So, white ball will be more likely to be picked out of the box.

13.
The number of different types of toys Ashley has is shown in the circle graph. A toy is picked at random. Which type of toy is most likely to be picked?

 a. cars b. barbie dolls c. airplanes d. teddies

#### Solution:

The blue colored sector has the maximum area.

The blue colored sector represents the number of airplanes.

So, an airplane is most likely to be picked.

14.
From a box containing 4 burgundy, 3 white, 5 pink, and 16 lilac marbles, a marble is picked at random. Which marble is the most likely to be picked?
 a. pink marble b. burgundy marble c. lilac marble d. white marble

#### Solution:

The maximum number of marbles are lilac in color. So, the probability of picking a lilac marble is more than the probability of picking any other marble.

So, a lilac marble is most likely to be picked.

15.
Which color would you bet on, if you are playing a game with the spinner shown?

 a. blue b. green c. red d. yellow

#### Solution:

Since the blue colored sector has the maximum area, the probability to land on blue is more than for any other color.

So, it is better to bet on blue.

16.
The table shows the experimental probability values for balls of different colors picked at random from a box. Which ball is likely to be in larger number?
 Color Probability burgundy $\frac{5}{12}$ green $\frac{4}{12}$ blue $\frac{3}{12}$

 a. blue ball b. green ball c. burgundy ball d. None of the above

#### Solution:

The probability of picking a burgundy ball is more than the probability of picking any other ball.

So, burgundy ball is likely to be present in larger number.

17.
The number of different types of toys Tanya has is shown in the circle graph. Which type of toy is least likely to be picked if a toy is picked at random?

 a. An airplane b. A teddy c. A car d. A doll

#### Solution:

The pink colored sector has the minimum area.

The pink colored sector represents the number of dolls.

So, a doll is least likely to be picked.

18.
The table shows the experimental probability values for balls of different colors picked at random from a box. Which ball is likely to be in larger number?
 Color Probability white 9/13 blue 2/13 black 2/13

 a. blue ball b. white ball c. black ball d. None of the above

#### Solution:

The probability of picking a white ball is more than the probability of picking any other ball.

So, white ball is likely to be present in larger number.

19.
Are all possible outcomes for spinning the spinner shown 'equally likely as unlikely'?

 a. No b. Yes

#### Solution:

The spinner is divided into 5 sections. These five sections are not of equal area.

So, all possible outcomes for spinning the spinner shown are not 'equally likely as unlikely'.
