Question

The distribution of marshmallows in a box of cereal is given in the probability model. Determine the probability that a randomly selected marshmallow will be a rainbow shape. Enter your answer as a decimal rounded to the hundredths place. P(Rainbow)=

a) 0.25
b) 0.33
c) 0.50
d) 0.75

Answer 1

The probability of selecting a rainbow-shaped marshmallow is 0.25.

Step-by-step explanation:

To determine the probability that a randomly selected marshmallow will be a rainbow shape, we need to look at the probability model. There are four possible shapes: round, star, rainbow, and square. The distribution of the marshmallows is not given, so we cannot calculate the exact probability. However, since there are four shapes and each shape is equally likely, the probability of selecting a rainbow shape is 1 out of 4, which can be represented as 0.25.
