The probability that a woman will die from breast or cervica

The probability that a woman will die from breast or cervical cancer is .00027. Find the probability that, of the10,000 women who are monitored for breast or cervical cancer,

A. Three will die from breast or cervical cancer.

(b) At most four will die from breast or cervical cancer.

(c) At least two will die from breast or cervical cancer.

Solution

a) three will die means exactly 3 will die so 9997 won\'t die so probability = ((0.00027)^3) * ((1-0.00027)^9997) b) atmost 4 will die means atleast 9996 won\'t die so (1-0.00027)^9996 and we don\'t have to make any restriction on remaining four c) atleast two will die so (0.00027)^2 and we don\'t have to make any restriction on remaining 9998
