A basketball player shoots 10 shots, and has a 60% chance of making each shot. a) What is the probability that she makes exactly 4 of the 10 shots? b) What is the probability that she makes at least 3 of the 10 shots?
Added by John S.
Step 1
6 Plugging in the values: \[ P(X = 4) = \binom{10}{4} \times 0.6^4 \times (1-0.6)^{10-4} \] \[ P(X = 4) = \binom{10}{4} \times 0.6^4 \times 0.4^6 \] \[ P(X = 4) = 210 \times 0.1296 \times 0.4096 \] \[ P(X = 4) = 0.1115 \] Show more…
