Question

Two true-breeding snapdragon (Antirrhinum majus) plants, one with red flowers and another with white flowers were crossed. The F1 plants were all with pink flowers. When the F1 plants were selfed, they produced three kinds of F2 plants with red, pink and white flowers in a 1:2:1 ratio. The probability that out of the five plants picked up randomly, two would be with pink flowers, two with white flowers and one with red flowers is _____%.

Answer 1

I don't know you understand small quantities likho

Answer 2

The probability that out of the five plants picked up randomly, two would be with pink flowers, two with white flowers and one with red flowers is __1/256___%.

• Probability of red = 1/4
• Probability of pink = 2/4 = 1/2
• Probability of white = 1/4
• Final probability out of five plants picked up randomly, 2 would be with pink, 2 with white and one red is = (1/2)^2*(1/4)^2*(1/4) = 1/256.
