There are two spinners. Each spinner is numbered 1-4. Each spinner is spun once. Find the probability of spinning each of the following:2 on the first spinner and a 4 on the second spinner, both numbers the same, 3 on exactly one spinner, one number less than the other.
prob(2 on 1st, 4 on 2nd) = (1/4)(1/4) = 1/16
prob(both a 3) = (1/4)(1/4) = 1/16
third question: 3 on one, one less on the other ???
do you mean (3,2) and (2,3)
if so , then prob = 1/16 + 1/16 = 1/8
Would you choose a two-way table or a tree diagram to display the possible outcomes for this situation?explain your choice.
You have to find the letter and then count!!! You see xD
