A fair decimal die is tossed five times. Find the probability of obtaining an odd number of even digits.

Step-by-step explanation:

Well, an even decimal die has probability 0.5 of rolling even and 0.5 of rolling odd.

->The chances of rolling exactly one even number on five rolls is

->The chances of rolling exactly three even numbers on five rolls is

The chances of rolling exactly five even numbers on five rolls is

Further, the probability of independent events is the sum of their probabilities, so the probability of rolling an odd number of even numbers is

step-by-step explanation:

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
