The probability that fewer than 4 of them are successful are 0.9527

<u>Explanation:</u>

Given:

number of trials, n = 6

p(successful) = 0.85

P(x >= 4) = ?

The problem can be solved using binomial probability formula.

 P(x >= 4) = 1 - binomcdf(6,0.85,4) = 1 - 0.0473

               = 0.9527

Therefore, the probability that fewer than 4 of them are successful are 0.9527

mojhsa [17]

Answer:

Lisa invest "$2180.81" in her bank.

Step-by-step explanation:

The given values are:

On Lisa's 62nd birthday,

she withdraw = $10,000

The annuity of $A will remain at 3 percent for 40 years. The retirement pension of $10000 lasts 23 years at rate percentage of 3 but begins 40 years later.

⇒  A\times (\frac{P}{A} ,3 \ percent,40) - 10000 (\frac{P}{A} ,3 \ percent,23)\times \frac{1}{(1.03)40} = 0

⇒  A\times 23.1148 - 10000\times 16.4436\times 0.3066 = 0

⇒  A = 10000\times 16.4436\times \frac{0.3066}{23.1148}

⇒      = 10000\times 16.4436\times 0.0132

⇒      =2180.81 ($)
