Answer: 7
Step-by-step explanation:
denotes the intersection of A and C, or in other words, how many elements are shared between them.
The number of elements is 2 + 5 = 7
The probability of the first event with x possible outcomes is equal to x/30. Also, the probability of the second event with y possible outcomes is y/29.
(1) P of 2 digit number, 21/30
P that the number is 4 is 1/29
Multiplying both probabilities will give us 7/290
(2) P that number is 19 is 1/30
P that the number is multiple by 4 is 6/29
The answer is 1/145
(3) P that number is 24 is 1/30
P that number is less than 15 is 14/29
The answer should be 7/435.
(4) P that number 1st number is perfect square is 5/30
P that second number is perfect square is 4/29.
The answer is 2/87.
Answer:
200 is the answer
Step-by-step explanation:
keep in mind 3*2=6
So 30% is 0.3
0.3*200=60
Hello,
I dont care for points, Just glad to help! :D
And A slope iis only x*y=z. This mean's
That you will basically be dividing top from side (NOY BOTTOM)
and be multiplying those 2.
Hope this helps
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)
