A pink-flowering plant is of genotype RW. If two such plants are crossed, we obtain a red plant (RR)with probability 0.24, a pink plant (RW or WR) with probability 0.58, and a white plant (WW) withprobability 0.18, as shown in the table. What is the expected number of W genes present in a crossingof this type?The expected number of white genes (W) is.(Type an integer or a decimal.)Number of W Genes PresentX₁012P₁0.240.580.18

In a survey of U.S. adults with a sample size of 2082, 370 said Franklin Roosevelt was the best president since World War II. Two U.S. adults are selected at random from this sample without replacement. Complete parts (a) through (d). (a) Find the probability that both adults say Franklin Roosevelt was the best president since World War II. The probability that both adults say Franklin Roosevelt was the best president since World War II is O. (Round to three decimal places as needed.)

When a scientist conducted a genetics experiments with peas, one sample of offspring consisted of 927 peas, with 723 of them having red flowers. If we assume, as the scientist did, that under these circumstances, there is a 3/4 probability that a pea will have a red flower, we would expect that 695.25 (or about 695) of the peas would have red flowers, so the result of 723 peas with red flowers is more than expected. a. If the scientist's assumed probability is correct, find the probability of getting 723 or more peas with red flowers. b. Is 723 peas with red flowers significantly high? c. What do these results suggest about the scientist's assumption that 3/4 of peas will have red flowers?

A pink-flowering plant is of genotype RW. If two such plants are crossed, we obtain a red plant (RR) with probability 0.24, a pink plant (RW or WR) with probability 0.53, and a white plant (WW) with probability 0.23, as shown in the table. What is the expected number of W genes present in a crossing of this type? The expected number of white genes (W) is (Type an integer or a decimal.) Number of W Genes Present Xi Pi 0 0.24 1 0.53 0.23
