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:
29 + 33 = 62
6 + 7 > 12
number one is 33
number two is d = 7
Step-by-step explanation:
Convert the speeds of Amir and Ryder to meters per second (m/s).
Amir:
8260 mm/s = 8.260 m/s
Ryder:
930 cm/s = 9.30 m/s
9.30 m/s > 8.260 m/s, so:
Ryder ran approximately 1 meter per second faster than Amir.
