The probability any one system works is 0.99
So the probability of any one system failing is 1-0.99 = 0.01, so basically a 1% chance of failure for any one system
Multiply out the value 0.01 with itself four times
0.01*0.01*0.01*0.01 = 0.000 000 01
I'm using spaces to make the number more readable
So the probability of all four systems failing is 0.00000001
Subtract this value from 1 to get
1 - 0.00000001 = 0.99999999
The answer is 0.99999999 which is what we'd expect. The probability of at least one of the systems working is very very close to 1 (aka 100%)
Answer:
Molly's
Step-by-step explanation:
The recipe with a stronger lemon flavor will have a greater ratio of lemon juice to water.
To find the ratio, divide the number of cups of lemon juice by the cups of water for each recipe:
Erica's recipe:
1/3
= 0.33
Molly's:
3/8
= 0.375
Since 0.375 is bigger than 0.33, this means Molly's recipe has a greater ratio of lemon juice to water.
So, Molly's recipe will have a stronger lemon flavor.
