Given : a basket contains 7 strawberries 5 blueberries and 3 grapes
two fruits are picked at random .
To Find : the probability that the first is strawberry and second is a Blueberry
Solution:
basket contains 7 strawberries 5 blueberries and 3 grapes
Total = 7 + 5 + 3
=> Total = 15
first is strawberry = 7/15
second is a Blueberry = 5/14
probability that the first is strawberry and second is a Blueberry
= (7/15)(5/14)
= (7/3)(1/14)
= (1/3)(1/2)
= 1/6
probability that the first is strawberry and second is a Blueberry = 1/6
