A: it would be 2 fives outta 8 then he picked one more bill out so chances are 4 fives outta 16. making it 1/4 of a probability.
Multilpy -2 on both sides of the < sign this will get u 1x < 24 in other words x < 24
When you roll two numbers you have four kinds of outcomes: EE, EO, OE, OO (where E = even, O = odd).
You get an even sum only if you sum two numbers that are both even or both odd, therefore the outcomes wanted are two: EE and OO.
Therefore:
P(sum is even) = 2 / 4 = 0.5
Hence, there is a 50% probability that, when you roll two numbers, their sum will be even.
Answer: (0.63, 7.07)
Step-by-step explanation:
The confidence interval for population proportion is given by :-
Given :
; 
Significance level : 
Critical value : 
Now, a 90% confidence interval for population proportion will be :-
Hence, a 90% confidence interval for population proportion = (0.63, 7.07)
