Question

Please help i dont understand

Answer 1

Given:

Number of spheres = 2

Number of prisms = 3

Number of pyramids = 5

To find:

The probability that a pyramid will be selected.

Solution:

We have,

Favorable outcomes = Number of pyramids

                                  = 5

Total outcomes = Total number of figures

                          = $2+3+5$

                          = $10$

Now, the required probability is:

$\text{Probability}=\dfrac{\text{Favorable outcomes}}{\text{Total outcomes}}$

$\text{Probability}=\dfrac{5}{10}$

$\text{Probability}=0.5$

Therefore, the probability that a pyramid will be selected is 0.5.
