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
Answer:
594
Step-by-step explanation:
22*3=66
66*3=198
198*3=594
You could just put 0 for a and b.
It would work.
Answer:
Step-by-step explanation:
Buying price = 375
Mark up = 25%
Mark up value = (25/100) * 375 = 93.75
Selling Price = buying price + markup value
Selling Price = 375 + 93.75
Selling Prince = 468.75
A quicker way (perhaps) is
Selling price = buying price (1 + 0.25)
Selling prince = 375*1.25 = 468.75
