Question

Six dice are thrown 729 times. How many times do you expect atleast 3 dice to show a 5 or 6 ?

Answer 1

Answer:

27

Step-by-step explanation:

Atleast 3 dice to get 5 or 6

probability to get 5 or 6 for one dice = 2/6

probability of 3 Dice to get 5 or 6 = (2/6)*(2/6)*(2/6)

Rest 3 dice have probability of 1 as they can get any number

Probability = 1/27

Thrown = 729 time

Chances = 729/27 = 27
