Calculate the probability that both bids are successful
Answer:
The probability that both contracs are successful is 0.21
Step-by-step explanation:
Given
E1 = the event that the bid on the first contract is successful
E2 = the event that the bid on the second contract is successful
P(E1) = 0.3
P(E2) = 0.7
Let P(A) represent the event that both contracts are successful
P(A) = P(E1 and E2)
Since both events are independent. P(A) becomes
P(A) = = P(E1 * P(E2)
By substituton
P(A) = 0.3 * 0.7
P(A) = 0.21
Hence the probability that both contracs are successful is 0.21
Answer:
45 students are in the Environmental Club
Step-by-step explanation:
25/100 = x/180 (cross multiply)
(180 * 25) / 100 = 45
Answer:
Balance after the withdrawals and deposit = $52.6Step-by-step explanation:
Savings account balance = $135.10
Total withdraws = $60 + $45 = $105
Deposit = $22.50
Balance after the withdrawals and deposit = Savings account balance + Deposit - Total withdraws
= $135.10 + $22.50 - $105
= $52.6
Answer:
k = 5
Step-by-step explanation:
k/2+1/2=3
Multiply each side by 2 to get rid of fractions
2(k/2+1/2)=3*2
k+1 = 6
Subtract 1 from each side to isolate k
k+1-1 = 6-1
k = 5
