Answer:
Step-by-step explanation:
A + B + C = 180
x + x - 24 + 68 = 180
2x - 24 + 68 = 180
2x + 44 = 180
2x = 180 - 44
2x = 136
x = 68
A = 68
B = 44
C = 68
The radius is 3.27 cm, because I used the formula in reverse.
Box 1 : 3 pencils + 7 pens = total of 10
probability of picking a pen is 7/10
box 2 : 3 pencils + 3 crayons = total of 6
probability of picking a crayon is 3/6 which reduces to 1/2
probability of picking both is (7/10 * 1/2) = 7/20 <==
Answer:
1 - 1/3
Step-by-step explanation:
Since 1/2 * 2/3 = 1/3, it should be the case that 1/3 divided by 2/3 gives 1/2 and that 1/3 divided by 1/2 gives 2/3. To divide fractions, we multiply the numerator by the reciprocal of the denominator, where the reciprocal of a number just interchanges the numerator and denominator of the number.
Answer: 0.5
Step-by-step explanation:
Given
There are 3 blue and 1 yellow marble
The chance of picking two marble out of 3 is 
The total no of ways of picking 2 marbles out of 4 is 
Therefore, the probability of picking 2 blue marbles
