The probability that at least 2 boys choose the same type of watch is 0.6181.
What is Probability?
Probability has been introduced in Maths to predict how likely events are to happen. The meaning of probability is basically the extent to which something is likely to happen.
Here, the total number of combinations of styles for 5 boys
12 X 12 X 12 X 12 X 12 = 12⁵
the total ways that each boy have different styles
12 X 11 X 10 X 9 X 8
P(None of the boys have same style) = (12 X 11 X 10 X 9 X 8) / 12⁵
= 0.3819
P(at least 2 boys have same style) = 1 - P(None of the boys have same style)
= 1 - 0.3819
= 0.6181
Thus, the probability that at least 2 boys choose the same type of watch is 0.6181.
