If one of those automobiled is equally likely to have either 2 or 3 defective tires, what is P[(X = 2) U (X = 4)] = P(2 U 4)? x 0 1 2 3 4 P(x) .54 .12 .20
Consider a variable x that describes the number of under-inflated tire on a four-wheel automobile. The mass function is given by: p(0) 0.4, p(1)p(2)p(3) 0.1; p(4)0.3 a) Verify that this is a proper mass function b) Determine the expected value and the variance of this distribution. c) For what proportion of cars will the number of underinflated tires be within+1 standard deviation of the mean value?
