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.
Step-by-step explanation:
Here is a table.
Answer:
See Bottom!
Step-by-step explanation:
17) 9
18) 2.0000
19) 20000000000
20) 00.804
21) 266.0000000000
22) 15.00
23) 77.5
24) 830.0000000000
5 + 5 + 5 + 5 + 5 + 5 = 30 (6 bills)
1 + 1 + 1 + 1 + 1 = 5 (5 bills)
30 + 5 = 35 (11 bills)
