solve the question

Jar A contains 4 white and 2 black balls, jar B contains 5 white and 2 black balls, and jar C contains 1 white and 2 black balls. One ball is to be selected from each jar. What is the probability that the ball chosen from jar B will be white, given that exactly 2 black balls are selected? (Enter your probability as a fraction.) 5/19 x Show My Work (Optional) 0 [0/1 Points] There are two variants of the gene that determines ower position in pea plants, labeled A and T for 'axial' and 'terminal'. A is dominant to T meaning that only one copy of A is required to make the owers axial, whereas individuals must be of genotype 'IT to have terminal owers. In crosses between plants, each parent gives one of their two genes to the offspring with equal probability. Calculate the following probability. (Enter your probability as a fraction.) the probability that an offspring of an AT x AT cross has genotype AT, given that it has axial owers 7/8 x
