What's your question so I could help?
Answer:
-288
Step-by-step explanation:
<h3>Given AP</h3>
<u>To find,</u>
- The sum of first 18 terms
<h3>Solution</h3>
<u>The first and 18th terms as per the formula</u>
- t(1) = 3 - 2 = 1
- t(18) = 3 - 18*2 = 3 - 36 = -33
- S18 = 1/2*18(1 - 33) = 9*(-32) = -288
<u>Answer is</u> -288
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
Um I think it is 2,1 count over 2 then go up1
