I'll use 44.
This number broken down means 4 in the 10's place and 4 in the ones place
4(10)+4(1)= 40+4=44
Answer:
Probability that both such alarms fail is 0.03027
Step-by-step explanation:
Probability the alarm fails = 0.174 (this is calculated by dividing the percentage by 100 like: 17.4/100)
Probability that both such alarms fail = 0.174 * 0.174 = 0.03027
Answer: a) b)
<u>Step-by-step explanation:</u>
a) In order to get an even number, you have the 3 different scenarios:
1) Even, Even, Even, Even
2) Even, Even, Odd, Odd
3) Odd, Odd, Odd, Odd
<em>Order doesn't matter</em>
Add them up to get your answer:
b) If one die is a 2 and another is a 3 and the other two dice can be any number, then you have 1 possibility for a 2, 1 possibility for a 3, and 6 possibilities for each of the other two dice.
The rule is "whatever the input is, multiply it by 5, then subtract 2"
For example, if the input is 4 then 4*5 = 20 and 20-2 = 18
So in short, the input 4 leads to the output 18 as shown in the top row of the diagram.
The answer is the box on the bottom row, right hand side where it says "x 5" and "-2" in the two bubbles.
