Answer:
Step-by-step explanation:
Given that twenty-three percent of automobiles are not covered by insurance (CNN, February 23,2006).
considering the total number of vehicles, probability for a randomly drawn vehicle not covered by insurance = 0.23
Each vehicle can be treated as independent of the other
Hence X no of vehicles not covered by insurance is Binom with n = 35 and p - 0.23
a) the expected number of these automobiles that are not covered by insurance=E(x) =
b) the variance
=
Std dev = square root of variance = 2.4897
3x+7=-15
-7=-7
3x=-22
you cannot get the number only if it has a decimal
I want to say the third option but dont trust my opinion
<span>a + 6 for a = 10.
so
10 + 6 = 16
answer
</span><span>b)16</span>
