In all cases, the events are independent. That's why we have to multiply the results.
Probability that both numbers are greater than 6 if the same number can be chosen twice.
P = 3 / 9 * 3 / 9 = 1/9 because possible outcomes are the pairs (7,8), (7,9) and (8,9).
Probability that both numbers are less than 7 if the same number can be chosen twice
P = 6 / 9 * 6 / 9 = 4/9
Probability when both numbers are odd numbers less than 6 if the same numbers cannot be chosen twice
P = 3/9 * 2/8 = 1/12, odd numbers less than 6 are 1, 3 and 5. If the same number cannot be chosen depending on these numbers, we'll end up with 2 in possible outcome for the 2nd pair of the probability.
Probability that both numbers are even numbers if the same numbers cannot be chosen twice is
P = 4/9 * 3/9 = 4/27. The same logic is possible in this case, as well
Answer:
Is exponential
Step-by-step explanation:
(B) Base: 3
B X Y
3^1=3
3^2=9
3^3=27
3^4=81
3^5=243
PEMDAS needs to be used in this case.
P is for parentheses, so we have to perform addition in parentheses first.
68+7= 75
Then, we perform the next addition:
93 + 75=168

Answer: xy/2 cm²
Step-by-step explanation:
An isosceles triangle is a triangle that has two sides out of the three sides to be equal. The area of an isosceles triangle is given as:
= 1/2 × base × height
where,
base = xcm
height = ycm
Therefore,
Area = 1/2 × x × y
Area = xy/2 cm²
Log2 (x - 6)(x - 4) = log2 x
(x-6)(x-4) = x
x^2 - 10x + 24 - x = 0
x^2 - 11x + 24 = 0
(x-3)(x-8) = 0
answer is 8
