The probability that a student selected at random majors in engineering is 30% which is 0.3.
The probability that the student both majors in engineering and play club sports is 10% which is 0.1.
For a student who is selected at random to be one who majors in engineering, there are two possible ways.
The student majors in engineering OR the Student both majors in engineering and plays club
The Probabilty that the student majors in Enginnering =
The probability that the student majors in engineering plus the probability that Student both majors in engineering and plays club sport
= 0.3+0.1= 0.4
First, since we're told there is a 29% discount on the original price, then $213 must be 71% of the original price because 100%-29%=71%. Then, it is also important to realize that we should use the decimal form of 71% which is 0.71. This is found by dividing 71 by 100 or simply moving the decimal point twice to the right. Then, we can write the equation 0.71x=213 where x represents the original price. This equation is essentially saying that 71% of some price is equal to $213. To solve this equation, you have to divide both sides by 0.71 to get x=$300 which is the final answer.
I hope this helps.
