Question

JA (b) B (cAnB (d) (AUB) 2-25. In control replication, cells are replicated over a period of two days. Not until mitosis is completed can freshly synthesized DNA be replicated again. Two control mechanisms have been identified-one positive and one negative. Suppose that a replication is observed in three cells. Let A denote the event that all cells are identified as positive, and let B denote the event that all cells are nega- tive. Describe the sample space graphically and display each of the following events: (a) A (c) An B (b) B (d) (AUB)

Answer 1

Sample space will be the three cells where the replication has been observed.

Given Event A = all the cells are identified as positive

Event B = All the cells are identified as negative.
