A= 20 times 20 - (20 - 2 times 3) times (20-2 times 3) this equal 336
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
=
=
Now, the required probability is:
Therefore, the probability that a pyramid will be selected is 0.5.
