Random sampling is when you select a random group of people for something.
Ex. Out of a population of 259,096 people, a random sample of 400 people are choosen.
3y + 4 = 11y
(take away 3y from both sides)
4 = 8y
(divide by 8 on both sides)
0.5 = y
y = 0.5
Answer:
36
Step-by-step explanation:
With no parenthesis
To find the total probability, we first need to solve for the probability of the individual events.
Event 1:
P(consonant)=7/11
We know this to be true because out of the 11 total possibilities for the event, 7 of them are consonants.
R E P L A C E M E N T
Event 2
P(e)=3/10
We know this to be true because out of the 10 total possibilities for the event (since we didn't replace the first card we withdrew), 3 of them are the letter 'e'.
R E P L A C E M E N T (-1 to account for the first card we withdrew)
The possibility of both events...
P(consonant then 'e')=7/11*3/10=21/110
Answer: P=21/110
