The probability that 5 or less of the inspected firms that will result smog volation is 0.944.

Given that among 50 different industrial firms, 15 violate smog regulations and the sample size be 10.

We are required to find the probability that 5 or less of the inspected firms that will result smog violation.

Probability is basically the calculation of likeliness of happening an event among all the events possible. It lies between 0 and 1.

Probability=Number of items/ Total items.

Probability that the firm violates the regulations if 1 industry is chosen from 50 industrial firms=15/50=0.3

Probability that 5 or less of the inspected firms will result somg violations among 10 industrial firms=10C_{0}(0.3)^{0} (0.7)^{10}+  10C_{1}(0.3)^{1} (0.7)^{9}+10C_{2}(0.3)^{2} (0.7)^{7}+10C_{3}(0.3)^{3} (0.7)^{7}+10C_{4}(0.3)^{4} (0.7)^{6}+10C_{5}(0.3)^{5} (0.7)^{5}

=0.028+10*0.3*0.04+45*0.09*0.057+120*0.027*0.082+

210*0.0081*0.117+252*0.00243*0.16807

=0.028+0.12+0.23+0.265+0.199+0.102

=0.944

Hence the probability that 5 or less of the inspected firms that will result smog volation is 0.944.

Estimate the figure to the nearest whole number
olya-2409 [2.1K]
That means that, for example:

 if your number is 49 the nearest whole number would be 50.

so by saying estimate the figure to the nearest whole number , they are basically saying find your nearest whole number.
