Answer:
99.96%
Step-by-step explanation:
Given the information:
=> the are 25 people in total
Hence, the total possible outcomes of all the members in the 4 committee:
They want us to find the probability that the committee will consist of at least one student, which means that
=(Total possible outcome - committee with no student) / Total possible outcomes
So we need to find the possible outcomes of committee with no student:
= 
=> the probability that the committee will consist of at least one student.
= (12650 - 5) / 12650
= 0.9996
= 99.96%
Hope it will find you well.
Answer:
243
Step-by-step explanation:
If there is one question that has three choices a1, a2, and a3, then there will be 3 i.e. 3¹ different ways of answering which are a1 or a2 or a3.
If there are two questions that have answer choices a1, a2, a3 and b1, b2, b3 then there will be 9 i.e. 3² different ways of answering which are a1-b1, a1-b2, a1-b3, a2-b1, a2-b2, a2-b3, a3-b1, a3-b2, and a3-b3.
Similarly, when there are 5 questions that have three choices each, then there will be 3⁵ i.e. 243 ways of answering options. (Answer)
Answer:
-2.6, -0.4, 0, 0.8, 1.2
Step-by-step explanation:
First, change each mixed fraction into improper
2 3/8 = 19/8
1 3/4 = 7/4
The problem will look like: (19/8)/(7/4)
To solve, flip the second fraction, and change the division sign into a multiplication sign.
(19/8)/(7/4) = (19/8) x (4/7)
Multiply across
(19/8) x (4/7) = 76/56
Simplify.
76/56 simplified = 19/14
Change to mixed fraction
19/14 = 14/14 + 5/14 = 1 5/14
1 5/14 is your answer
hope this helps
A exponent is the smaller number you will see sometimes on the top of a number or to the right of it but smaller than normal font
