The probability that a student, chosen at random, does not study chemistry is 20/41.
<h3>
What is Probability?</h3>
Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event. For an experiment having 'n' number of outcomes, the number of favorable outcomes can be denoted by x. The formula to calculate the probability of an event is as follows.
Probability(Event) = Favorable Outcomes/Total Outcomes = x/n
Here, Total number of student = 41
Student who does not study chemistry = 20
So, the probability = favorable outcome / total outcomes
P(not studying chemistry) = 20 / 41
Thus, The probability that a student, chosen at random, does not study chemistry is 20/41.

Answer:
$490
Step-by-step explanation:
Shauna spent $175 on a pair of shoes.
She spent 1/9 of the remaining money on a shirt.
If he still had 4/7 of his money left,how much did he have at first ?
Solution:
Let at first, Shauna have =
Money spent on a pair of shoes = $175
Remaining money =
<u>As she spent 1/9 of the remaining money on a shirt.</u>
Money spent on shirt =
As he still had of his money left:-
Money left =
Money left with Shauna = Total money, she had at first -(Money spent on a pair of shoes + Money spent on shirt )
Subtracting both sides by and adding both sides by
Taking LCM of 7 and 9, we get 63
Adding both side by -
By cross multiplication:
Dividing both sides by 180
Therefore, total $490, she had at first.
