A fair 10 sided spinner has sides numbered 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9.
Write down the name of the distribution that can be used to model the number the spinner lands on from each spin.
The spinner is spun 20 times. The random variable X X\,X represents the number of times the spinner lands on 8. Find the probability that the spinner lands on 8 exactly 2 times.
Find P(1≤X<3)P(1 \leq X < 3)P(1≤X<3)
