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
