Answer:

0.9562

Step-by-step explanation:

Binomial probability is mathematically expressed as:

$P(X=x)={n\choose x}p^x(1-p)^{n-x}$

Given that p=0.18, n=5 , is calculated as:

$P(X\leq 2)=P(0)+P(1)+P(2)\\\\={5\choose 0}0.18^0(1-0.18)^5+{5\choose 1}0.18^1(1-0.18)^4+{5\choose 2}0.18^2(1-0.18)^3\\\\=0.3707+0.4069+0.1786\\\\=0.9562$

Hence, the probability of no more than 2 successes in 5 trials is 0.9562

Y=x-3 what is my answer

ale4655 [162]

Answer:

x = 3 or y = -3

Step-by-step explanation:

To find x, substitute y with a 0.

0=x-3. Minus the x on both sides and x will equal 3

To find y, substitute x with a 0.

y=0-3. 0-3 equals -3 which means that y will equal -3
