The probability of having homework tonight is 1/6. what is the probability of not having homework tonight?

Probability of not having homework tonight is

Step-by-step explanation:

Given that the probability of having homework tonight is . we have to find the probability of not having homework tonight.

As total probability is 1 i.e

P(occurring an event)+P(not occurring an event)=1

⇒ P(having homework tonight)+P(not having homework tonight)=1

⇒  +P(not having homework tonight)=1

⇒ P(not having homework tonight)=

Hence, Probability of not having homework tonight is

step-by-step explanation:

i am not sure sorry : c

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
