Calculate the probability that they both take a square.

Answer 1

Given:

• total no.of shapes = 5
• 4 squares and one circle

To find:

• probability that they both get squares =?

Solution:

p( both get square) =chance to getsquare

total no.of shapes

chances of getting square = 2 ( as both take each shape)

= 2/5

I think iam right if not pls tell me :)
