A marketing research shows that for every 100 flyers distributed to potential customers, 1.2 customers will be captured. If 10000 flyers are being distributed, find the probability that 150 customers are captured?

10,000 is 100 times 100

so 100 *1.2 = 120
so we got more
binomial probability distribution:
https://probabilityformula.org/binomial-probability-formula.html
p = probability of success = 1.2/100 = 0.012
q = 1 - p = 1 - 0.012
r = successes 150
n = number of trials = 10,000
p of 150 out of 100,000 = C(10000 , 150) 0.012^150 * (1-0.012)^9850
where C(10000 , 150) = 10000 ! / [ 150! (9850 !) ]
