Suppose a fair die numbered 1 to
7
is rolled
4
times. Complete parts (a) and (b) below.(a) Find the probability distribution for the number of times
7
is rolled.
+37146 If it is a fair die 7 should be rolled 1 time out of 7 or 1/7 of the time 1/7 x 4 rolls = 4/ 7
+220 The probabilility of a dice 1-7 rolling on a 7 four times is very low. Here's how:
The expression 1/7*1/7*1/7*1/7 or (1/7)^4 is to be evaluated to find the answer.
That is, 1/49*1/49 which equals 1/2401 which equals approximately ~.0004.
The probability is approximately ~0.04%.
