According to a survey in one U. S. city, 53% of women between the ages and 25 of 35 are married, 45% are working full time, and 21% are married and working full time. If a woman between the ages of 25 and 35 is picked at random from the city, what is the probability that she is working full time or married but not both

56%

Step-by-step explanation:

given data:

married women between 25 and 35 = 53%

working full time = 45%

married  and working full time = 21%

Solution:

= 53% - 21%

= 32%

= 45% - 21%

= 24%

probability that she is working full time or married but not both

= 32% + 24%

= 56%

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
