what is Pr(E U F)?
2. Your drawer contains 8 red socks and 6 green socks. it is too dark to see which are which.
Choose 2 socks. What is the probability that you pick a pair of socks ( either 2 red or 2 green)
3. In a school of 1200 students, 250 are seniors, 150 students take math, and 40 students are seniors and are also taking math
what is the probability that a randomly chosen student who is a senior, is taking math?
4. Cross-fertilizing a red and a white flower produces red flowers 25% of the time. now we cross-fertilize pairs of red
and white flowers and produce five offspring. what is the probability that there are no red flower plants in the five offspring?

There is a two locus, two allele system where the ‘E’ locus codes for flower color and (EE) gives red flowers and (ee) gives white flowers and (E) is dominant. The second locus controls seed color and has two alleles, (YY) gives yellow seeds and (yy) gives green seeds and (Y) is dominant. Assuming these loci are on different chromosomes (that is, they are unlinked) what will be the genotype frequencies of the offspring be in a cross between EE...
