A container holds 20 red, 20 blue, and 10 green marbles. is the probability of choosing a blue marble greater than or less than
the probability of not choosing a blue marble? Explain.

the probability of choosing is blue marble is less than the probability of not choosing a blue marble

Step-by-step explanation:

the reasoning for this is that there are 50 marbles and only 20 of the 50 are blue. Which means that 30 are not blue. Since 30 is bigger and 20 (ie. there are more non-blue marbles than there are blue marbles), the probability of choosing a blue marble is less than the probability of not choosing a blue marble

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
