Alina [70]

There are a total of 20 hamsters. I solved it by dividing the 8 hamster by 2 to get what 1/5 would be. After i know 1/5=4 hamsters i multiplied 4*5

4 hamsters is the same as 1/4 of all the hamster

8 hamsters=2/5

12 hamster=3/5

16 hamster=4/5

Answer:

$p = 56\% = 0.56 \\ n = 5 \\ q = 1 - p = 0.44 \\ P(X = x) = {n \choose x} {p}^{x} {q}^{(n - x) } \\ P(X < 2) = P(X = 0) + P(X = 1) \\ {5 \choose 0} {0.56}^{0} {0.44}^{(5 - 0) } + {5 \choose 1} {0.56}^{1} {0.44}^{(5 - 1) }$
