Example: A (pseudo) random number generator on the computer can give a sequence of independentrandom digits chosen from S = {0, 1,...,9}. This means that (i) each digit has probability of ofbeing any of 0, 1,..., 9, and (ii) the outcomes for the different trials are independent of one another.We call this type of setting an "experiment with independent trials". Determine the probability that(a) in a sequence of 5 trials, all the digits generated are odd(b) the number 9 occurs for the first time on trial 10.

What if we toss the coin four times? A) The probability changes for both three and four tosses. B) The probability changes if we toss the coin four times, but does not change if we toss the coin three times.
