A survey of cars showed that the probability distribution of X is as follows. 1 2 3 4 5 P(x) 0.62 0.12 0.09 0.03 0.14 Download data LOADING 0% Part 1 Find P (5). P (5) -10.14 Part 2 out of 7 Find P (Less than or equal to 2). P (Less than or equal to 2)-

Answer 1

Solution

Given that

a ) P ( X = 5 )

= 0.14

P (5 ) =0.14

b ) P ( X $\leq$ 2 )

= P ( X = 1 ) + P ( X = 2 )

=0.62 + 0.12

= 0.74

Probability = 0.74
