I only had 11 questions and these are the answers for those of you who have 11
oOF still no answers huh
I need full answers to the test please
1. is 1/6 It's very simple, take the amount of cards in a hat and take the amount of cards that fit the criteria that you need to take out.
Still waiting for your answer choices, so we can check them
Meantime, make sure you know the distinction between "probability" and "odds"
I will do #5 for you to show that difference
5. M-O-N-T-A-N-A ---> 3 vowels out of 7 letters
Prob(picking a vowel) = 3/7
Prob(not picking a vowel) = 4/7
What are the odds against picking a vowel
= Prob(not picking a vowel) : Prob(picking a vowel)
= 4/7 : 3/7
= 4 : 3
btw, the odds in favour of picking a vowel = 3 : 4
Do the others the same way
