Question

you spin a spinner and the probability that the spinner will land on red is 18%. Suppose you spin the spinner 4 times. What is the probability that the spinner will land on red at least 2 times?

Answer 1

This can be solved by the binomial distribution:
\[P(0\ red)=0.82^{4}=0.4521\]
\[P(1\ red)=4\times 0.18\times 0.82^{3}=0.3970\]
P(0 red) + P(1 red) = 0.8491
The probability that the spinner will land on red at least 2 times is
1.0000 - 0.8491 = ?
