I was having trouble solving this Binomial Distribution problem. For step 1, I keep getting "0.5" which is incorrect. Guidance is greatly appreciated in solving this multistep problem.

Step 1: According to genetic theory, the blossom color in the second generation of a certain cross of sweet peas should be red or white in a 3:1 ratio. That is, each plant has probability 3/4 of having red blossoms, and the blossom colors of separate plants are independent. What is the probability that exactly 8 out of 10 of these plants have red blossoms? The probability is, e Book O 0.0012 O 0.2816 O 0.5 O 0.01Step 2: According to genetic theory, the blossom color in the second generation of a certain cross of sweet peas should be red or white in a 3:1 ratio. That is, each plant has probability 3/4 of having rec blossoms, and the blossom colors of separate plants are independent. What is the mean number of red-blossomed plants when 130 plants of this type are grown from seeds? Fill in the blank: The mean number is: (Give your answer to one decimal place.)Step 3: According to genetic theory, the blossom color in the second generation of a certain cross of sweet peas should be red or white in a 3:1 ratio. That is, each plant has probability 3/4 of having red blossoms, and the blossom colors of separate plants are independent. What is the probability of obtaining at least 90 red-blossomed plants when 130 plants are grown from seeds? The most exact answer is, O 0.0489 O 0.0134 O 0.9357 O 0.9511
