What is the probability of flipping a coin 15 times and getting tails 10 times?

This is found using the binomial distribution   with P(H) = 1/2 and P(T) = 1/2  n = 15 and r = 10

= nCr(0.5)^(15-10)(0.5)^10

=  15C10 * 0.5^15  =  0.0916   or  9.16%

200 miles.45 x 3 (charge per day times days)135$205$ - 135$ = 70$0.35x = 70divide both sides by 0.35200

Do the inverse operation
