Title:
Step-by-step explanation:
It is given that, if 100 persons book their seats, then only 88 passengers come.
The probability of 1 passenger to come is [tex]\frac{88}{100}[/tex] = 0.88.
There will not be enough seats only when, 331 or more than 331 passengers will come.
The probability of 1 passenger will not come is (1 - 0.88)= 0.12.
Out of 354 passengers the probability that n passengers will come is [tex]^{354}C_n (0.88)^n (0.12)^{354 - n}[/tex].
The required probability is ∑[tex]^{354}C_n (0.88)^n (0.12)^{354 - n}[/tex], where [tex]331\leq n \leq 354[/tex].
