P of 1st white marble = 4/ 12
and P of 2nd white in a row = 3 /11
total = ( 4/12) * ( 3/11)
= 1/11
hope it helped
Answer:
Given that,
You roll a special 44-sided die.
To find the probability that the number rolled is a "1" or a "2"
Total sample space= 44
Probability that the number rolled is a "1" is,
Probability that the number rolled is a "2" is,
By addition rule we get that,
Probability that the number rolled is a "1" or a "2" is,
Answer is:
Answer:
The radius of the cylinder is 2.92 cm
Explanation:
Given:
Volume of cylinder, V = 193 cm³
Height of the cylinder, h = 7.2 cm
Radius of the cylinder, r = ?
We know:
Volume of cylinder = πr²h
On substituting the value we get:
193 = 3.14 X r^2 X 7.2\\\\r^2 = 8.54\\\\r = 2.92 cm
Therefore, the radius of the cylinder is 2.92 cm

Answer:
x = -7/2
Step-by-step explanation:
(1/4) ^ (x+1) = 32
Rewriting 32 as 2^5 and 1/4 and 2^-2
2^-2 ^ (x+1) = 2^5
We know that a^b^c = a^ ( b*c)
2 ^ (-2x-2) = 2 ^ 5
Since the bases are the same, the exponents have to be the same
-2x-2 = 5
Add 2 to each side
-2x = 7
Divide by -2
x = -7/2
