Answer:
There are five dollar bills and ten dollar bills.
Step-by-step explanation:
Given:
Selling price of bicycle .
The friend gave five dollar bills and ten dollar bills.
Total number of bills .
To find: Number of five dollar bills and ten dollar bills the friend gave.
Solution:
The friend gave five dollar bills and ten dollar bills and the friend gave bills in all.
So, .
Selling price of bicycle .
So,
Putting the value of from equation in equation .
Now, putting the value of in equation .
Hence, there are five dollar bills and ten dollar bills.
2, 3, 5, 1000 any number that is larger than 1.
Answer:0.0081 or 0.81%
Step-by-step explanation:
The required probability is P(3,5,0.1)= C5 3 * p^3*q^2, where
C5 3= 5!/3/2=4*5/2=10
p is the probability that one randomly selected calculator is defective= 10%=0.1
q is the probability that one randomly selected calculator is non-defective.
q=1-p=1-0.1=0.9
So P(3,5,0.1)= 10*0.1^3*0.9^2=0.01*0.81=0.0081
Step-by-step explanation:
the probability of A working is 60% or 0.6, so the probability it does not work is 40% or 0.4.
the probability of B working is 90% or 0.9, so the probability it does not work is 10% or 0.1.
plan 1
it is the probabilty that either A works, or (if it is not working) B works.
0.6 + 0.4×0.9 = 0.6 + 0.36 = 0.96
plan 2
either B works, or (if it is not working) A works
0.9 + 0.1×0.6 = 0.9 + 0.06 = 0.96
both plans have the same success probability.
