Question

33) A student has a set of cards, Each cara nas a picture of one shape.

The table shows the number of cards that have a picture of each
shape. The student will randomly select one card from the set.
Shape Cards
Circle = 8
Pentagon = 12
Rectangle = 10
Square = 6
Triangle = 4

Which statement is true?

A) The probability of selecting a card with a picture of a circle is 5/8, and the probability of selecting a card that is not a picture of a circle is 3/8

B) The probability of selecting a card with a picture of a circle is 3/8, and the probability of selecting a card that is not a picture of a
circle is 5/8

C) The probability of selecting a card with a picture of a circle is 1/5, and the probability of selecting a card that is not a picture of a
circle is 4/5

D) The probability of selecting a card with a picture of a circle is 4/5, and the probability of selecting a card that is not a picture of a circle is 1/5

Answer 1

1L= m3
1cl= dm3
1g= t

Answer 2

Answer: C The probability of selecting a card with a picture of a circle is 1/5, and the probability of selecting a card that is not a picture of a

circle is 4/5

Explanation:

First you need to find the total amount of cards in the set by adding up all of the cards: 8 + 12 + 10 + 6 + 4 = 40

Then to find the probability of selecting a circle divide the number of cards that have a circle by the total number of cards: 8/40

You can simplify it to be 1/5 since 8/8 = 1 and 40/8 = 5

So the probability of a circle is 1/5

This means that the probability for all of the other shapes that are not a circle have to be 4/5-- but you can check by adding up the rest then dividing by 40:

12 + 10 + 6 + 4 = 32

32/40 --> 32/8 = 4 & 40/8 = 5

4/5
