Frank starts off with $ 120 to spend on his shirts and shoes. Frank buys 3 shirts for $15.50 each. Shoes cost $32.50 each per pa

evablogger [386]

Shirts: 3 x 15.50 = 46.50

120 - 46.50 = 73.50 left to spend on shoes

73.50/32.50(cost per pair) = 2.26....so he was able to purchase 2 pairs of shoes.

Among 9 electrical components exactly one is known not to function properly. if 4 components are randomly selected, find the pro

seraphim [82]

Answer:

0.4444

Step-by-step explanation:

Use the following property to ease the calculation:

P(At least one)=1-P(None)

Total number of electrical components: 9

Number that does not function well :1

Number that functions well : 8

We have $^8C_4=70$ ways to to choose 4 good components from 8.

We have $^9C_4=126$ ways to choose 4 components from a total of 9.

If all function properly then none is bad, we $^1C_0=1$ way to do this.

P(At least one)= $1-\frac{^8C_4*^1C_0}{^9C_4}$

P(At least one)= $1-\frac{70*1}{126}$

P(At least one)=0.4444
