Question

Jordan trolls a fair dice 216 times how many times would Jordan expect to roll a four

Answer 1

Answer:

36

Step-by-step explanation:

since a fair die has 6 sides (i.e 6 possible outcomes),

P (rolls a 4 on 1 roll) = 1/6

hence if he rolls the die 216 times, we would expect to roll a 4 for 1/6 of the time. I.e.

expected number of times to roll a 4

= (1/6) x 216 = 36 times.
