Consider flipping a weighted coin with the property that the coin comes up heads with probability p and tails with probability 1 − p. suppose that you flip the coin repeatedly until it comes up tails. let x be the random variable for the number of flips completed. find e[x] and var(x). you may use wolfram alpha or another tool to compute the value of any infinite sums.

f is the midpoint of

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12
