WebbThe expectation for number of trials, n + r is given by the general formula: r ( 1 − p) Given our known parameters: r = 1 and p = 0.5, E ( n + r; 1, 0.5) = r 1 − p = 1 1 − 0.5 = 2 Hence we can expect to make two tosses before getting the first head with the the expected number of tails being E ( n + r) − r = 1. WebbOn the other hand, the probability that at least 1 chip is defective is the probability that 1, 2, 3, or all 4 of the chips are defective, which may or may not mean that the last chip selected is defective. So P (SSSD) alone fails to take into account several other possibilities. WebbThus, at most one head means number of heads in probability favourable outcomes is 0 or 1. and at least one head means the number of head is greater than or equal to 1. At most one head means number of heads in probability is 0 or 1. At least one head means the number of head is greater than or ... thomas beach vacations myrtle beach sc
