Assume spinning of both spinners are random and independent of each other. Red spinner is labeled 1 to 6, consequently the event of spinning less than three is 1 or 2 (two outcomes) out of 6 possible outcomes for a probability of 2/6=1/3. Blue spinner has 4 sectors (4 possible...

3 and 6 are multiples of 3. The probability the either one or the other events would occur is obtained by adding the probability of the individual events. Probability = 1/6 + 1/6 = 2/6 = 1/3 2, 4 and 6 are even numbers = 1/6 + 1/6 + 1/6 = 3/6 = 1/2 The probability that both/...
