Two coins are simultaneously tossed until one of them comes up a head and the other a tail. the first coin comes up a head with probability p and the second with probability q. all tosses are assumed independent. (a) find the pmf, the expected value, and the variance of the number of tosses. (b) what is the probability that the last toss of the first coin is a head?

unless if u could do my questions, if not i wouldn't want to

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3

57.09 minus 7.0435 equals

step-by-step explanation:

just subtrach them both and u get the answer of 50.0465
