<em>The fair die</em> will roll 1 3 5 three times out of six or 3/6 which can be reduced down to 1/2.
<em>Chips </em>There are 3 chips all together. Two of them are red. That means that she has 2/3 chances of pulling up a red
Combine
When you have 2 events that are independent of one another, then the probabilities are multiplied together. The red chips cannot be left at 2/3 for example, because a "win" depends on the die coming up odd. The 2/3 must go down.
P(die_odd) * P(red_chip) = 2/3 * 1/2 = 1/3
Answer 1/3 <<<<

Notice the probability is lower than either one of the givens.

Answer:
Step-by-step explanation:
<u>The correct question is:</u> If the first, second and last term of an AP are a,b and 2a respectively, then show that the sum of all terms of an AP is 3ab/2(b-a).
Firstly, as we know that the nth term of an A.P. is given by the following formula;
, where a = first term of AP, d = common difference, n = number of terms in an AP and = last term
Since it is given that the first, second and last term of an AP are a,b and 2a respectively, that means;
first term = a
d = second term - first term = b - a
= 2a
So,
------------- [equation 1]
Now, the formula for the sum to n terms of an AP when the last term is given to us is;
{using equation 1}
Hence proved.
Answer:
They ran 0.75 of a mile.
Step-by-step explanation:
3/4 equals to 0.75.
Answer:
A) no because if a and b are both negative ab > 0.
B) yes the same sign leads to a positive product.
C) yes a and b just have to have the say sign
D) No because when a < 0 and b > 0, ab < 0
E) Yes a and b just have to have different signs for the product to be negative.
F) Yes different signs leads to a negative product
