Events with two possible outcomes are modelled by the following equation: if the probability of success is p, you have n trials, and X is the random variable representing the number of times the event with probability p happens, you have

\displaystyle P(X=k) = \binom{n}{k} p^k (1-p)^{n-k}

Now, you want X=0 (i.e. the event never happens). So, you have

\displaystyle P(X=0) = \binom{n}{0} p^0 (1-p)^{n-0} = (1-p)^n

What is 4 2/7 times 2 1/5
IrinaVladis [17]

Hey!

---------------------------------------------------

Steps To Solve:

~Find common denominators

4 2/7 = 4 10/35

2 1/5 = 2 7/35

~Turn into improper fractions

4 10/35 = 150/35

2 7/35 = 77/35

~Multiply

150/35 x 77/35 = 11,550/1,225

~Simplify

11,550/1,225 = 9 525/1,225 = 9 105/245 = 9 21/49 = 9 3/7
