It's not specified whether 1 is the 1st or 2nd roll: HOWER:
The 1st Roll is "1": P(odd sum/the 1st Roll is 1)
What is the sample space of all numbers starting with "1":
{(1,1), (1,2), (1,3), (1,4), (1,5), (1,6),} = 6
the couple of add sum=(1,2), (1,4), (1,6), =3
P(odd sum/ 1st is 1) = 3/6 =1/2
or in applying the formula:
P(odd sum/the 1st Roll is 1) =P(odd sum ∩ 1) / P(getting "1") it will give the same probability = 1/2
NOW if the 2nd Roll is "1", it 's still 1/2
1 true and false question = 1 / 2 chances
2 multiple choice question = 2/8
1/2 + 2/8 =
4/8 + 2/8 = 6/8.
6/8 = 3/4
you have a 75% chance of getting all 3 answers correct and getting a 100% on the quiz
hope this helps :D
Answer:
option-C
Step-by-step explanation:
we are given
Let P(A)=0.5
P(B)=0.9
P(A and B)=0.15
we know that
now, we can plug values
but we have
P(A)=0.5
we can see that both are not equal
so, A and B are not independent
so, option-C........Answer
Given:
treasury bond = 40,000
brokers commission = 600
interest rate = 12$ p.a
interest paid semi-annually, january 1 and july 1.
Since the treasury bond was sold on June 1, its interest revenue will only be equal to 1 month ( June 1 to July 1).
12% / 12 months = 1% per month
40,000 * 1% = 400 interest revenue to be recorded on July 1.
