A k out of n system is one in which there is a group of n components, and the system will function if at least k of the componen
ts function. For a certain 4 out of 6 system, assume that on a rainy day each component has probability 0.6 of functioning, and that on a nonrainy day each component has probability 0.9 of functioning. What is the probability that the system functions on a rainy day
2.15 1hr is 60 min so 60÷15=4 45miles×2hrs=90 45÷4=11.25 90+11.25=101.25 miles 101.25 miles÷ 25 miles per gallon= 4.05 gallons 4.05 gallons× $2.75 per gallon= $11.1375 $11.1375= $11.14 Alicia spends $11.14 on gas to get to work
