Question

2q is no i 11.) In a given one of Mende's hybridization experiments, the probability of offspring peas having green pods was % or .75. Consider breeding a group of ten such plants. b.) What would be the probability of seeing exactly four plants being green? Would you consider that an unusual outcome? Why or why not? ble c.) What would be the probability of seeing at least seven plants being green? prol ond Jts) 12.) Based on a Bellies survey of adults, there is a 48% probability that a randomly selected adult uses a tax preparer to file taxes. Find the probability that among 22 randomly selected adults, exactly 13 use tax preparers to file their taxes. Also, among 22 random adults, do you think that 13 is an unusually high number for those who use tax preparers to file their taxes? Why or why not?
