Suppose you toss a fair coin 10 times resulting in a sequence of heads (H) and tails (T). Let X be the number of times that the sequence HT appears. For example, HT appears thrice in THTHHTHHHT Find E(X). Hint: Use Indicator random variables.

Step-by-step explanation:

When it comes to statistics and probability, a random variable is a numerical explanation of the result of experimentation in statistics and probability. For a distinct random variable, x, the probability distribution is described by a probability mass function, which is denoted by f(x). This function offers the probability for every value of the random variable.

with btw u said 100pts but it clearly says

i answerd and just got 10pts

no hate

multiply length by height. multiply the length by the height, and then double the product. work out 10 x 10 results = 100 square inches, then work out 100 x 2 = 200. the answer is 200 square inches.
