Answer:
161 is your answer.
Step-by-step explanation:
Easy! If Kiersten has 23 balloons and Catherine has 8 times more than Kiersten, all we need to do is multiply. 23x8=184. Now to figure out how many more red balloons Catherine has compared to Kiersten we need to subtract Kiersten's amount from Catherine's amount. 184-23=161. So Catherine has 161 more red balloons than Kiersten.
The order Queen Zubaida picks a Satrap and a Vizier does not matter. Since order does not matter, combination is used.
Using a calculator, we solve for nCr = 12C2 = 66 ways..
Or using the combination formula C(n,r) = n!/[(n-r)!r!]
C(12, 2) = 12!/[(10!)(2!)] = 66 ways.
Answer: 11/243
Step-by-step explanation:
Each question has 3 options: 2 incorrect and 1 correct
Probability P(correct guessing) = 1/3
P(wrong guessing) = 2/3
Probability P(4 answers correct) = 5C4 × (1/3)^4 ×(2/3)^1
Probability P(5 answers guessed correctly) =5C5 ×( 1/3)5
Therefore Probability P(4 or more answers correct) = P(4) + P(5) = (10/3^5) +( 1/3^5)
P(4 or more correct answers) = 11/243
