Ответ:
From the information given,
Total number of chips = 7+3 = 10
Blue chips = 7
Yellow chips = 3
Therefore,
P(Blue chip) = 7/10
P(Yellow chip) = 3/10
In this regard, the probability of drawing a yellow chip on the second draw given that the first draw was a yellow chip remains the same.
That is,
P(Yellow chip on second draw) = 3/10
