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}=\frac{\text{Favorable outcomes}}{\text{Total outcomes}}`

`\text{Probability}=(5)/(10)`

`\text{Probability}=0.5`

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