When a certain type of thumbtack is flipped the probability of its landing tip up (U) is 0.52 and the probability of its landing tip down (D) is 0.48. Suppose you flip two such thumbtacks, one at a time. The probability distributor the possible outcome of these flips is shown below.
A. Find the probability of getting 0 ups, 1 ups, when flipping two thumbtacks
Given: Probability of landing tip up (U) 0.52 Probability of landing tip down(D) 0.48
two thumbtacks: Probability of getting 0 up, meaning 2 downs.: 0.48 * 0.48 = 0.2304 Probability of getting 1 up, meaning also getting 1 down: 0.52 * 0.48 = 0.2496
Addt'l Probability of getting 2 ups, no down: 0.52 * 0.52 = 0.2704
