Answer:
The probability is
Step-by-step explanation:
Let A be the event of one red, zero white, and three blue chips,
And, B is the event of at least three blue chips,
Since, A ∩ B = A (because If A happens that it is obvious that B will happen )
Thus, the conditional probability of A if B is given,
Now, red chips = 5,
White chips = 3,
Blue chips = 7,
Total chips = 5 + 3 + 7 = 15
Since, the probability of one red, zero white, and three blue chips, when four chips are chosen,
While, the probability that of at least three blue chips,
Hence, the required conditional probability would be,
