10 POINTS to whoever can help me with these word problems!?


1. The Alvin Secretarial Service procures temporary office personnel for major corporations. They have found that 50% of their invoices are paid within ten working days. A random of 10 invoices is checked. What is the probability that exactly 5 of the invoices will be paid within 10 working days?

2. A researcher wishes to conduct a study of the color preferences of new car buyers. Suppose that 40% of this population prefers the color green. If 20 buyers are randomly selected, what is the probability that between 2 and 6 (both inclusive) buyers would prefer green?

ANSWER NEEDS TO BE IN DECIMALS!!!

q1
answer
= 10C5 * 0.5^5 * 0.5^5
= 252 * 0.5^10
= 0.2461
= 24.6%

q2
answer
= 20C2*0.4^2*0.6^18 + 20C3*0.4^3*0.6^17 + 20C4*0.4^4*0.6^16 + 20C5*0.4^5*0.6^15 + 20C6*0.4^6*0.6^14
= 0.4^2*0.6^14 (190*0.6^4 + 1140*0.4*0.6^3 + 4845*0.24^2 + 15504*0.4^3*0.6 + 38760*0.4^4)
= 0.4^2*0.6^14 (1989.8016)
= 0.2495
= 24.95%

1. 25% i think....
2. about 4 i wud guess...

A. 100%
b.idk i don't really understand the qeustion bro srry
but the 1st one i'm pretty sure is right =]

hope i helped

If 50% of the invoices are paid in ten days, then out of 10 invoices, 5 would equal the 50%, so there is a 100% probability that 5 would be paid within 10 days.

Answer: 100%

1. 100%

2. 0%

40% of the 20 people is 8, meaning 8 people would prefer green.
