leonid [27]

The event that either M1 or M2 fails has probability

$P(M_1\text{ fails or }M_2\text{ fails})=P(M_1\text{ fails})+P(M_2\text{ fails})-P(M_1\text{ and }M_2\text{ both fail})$

by the addition rule. Failure events are independent, so

$P(M_1\text{ and }M_2\text{ both fail})=P(M_1\text{ fails})P(M_2\text{ fails})$

so that

$P(M_1\text{ fails or }M_2\text{ fails})=p_1+p_2-p_1p_2$

Denote this probability by $p$ . Then $X$ follows a geometric distribution with this parameter $p$ and has density

$P(X=x)=\begin{cases}(1-p)^{x-1}p&\text{for }x\ge1\\0&\text{otherwise}\end{cases}$

The expectation is $\dfrac1p=\dfrac1{p_1+p_2-p_1p_2}$ .

Step-by-step explanation:

A = P*e*r*t

P = 1,000

e = 2.71828

r = 0.09

t = 1

A = (1,000)*(2.71828)*(0.09)*(1)

A = 244.65

Radda [10]

Answer:

c=4.2

Step-by-step explanation:

using sine rule

c²=b² + a²-2ba cos C

c²=6²+5²-2x6x5cos95

c²=36+25-60cos95

c²=61-43.81

c²=17.19

c=√17.19

c=4.2
