Raul has 56 bouncy balls
he puts the balls into red gift bags and green gift bags
so lets say he puts x number of balls into green gift bags
then we are told that he puts three times as many balls into red gift bags as he puts into green gift bags
so the number of balls he puts into red gift bags is - 3 * x = 3x
the total number of balls = 56
so we can write the following equation
x + 3x = 56
4x = 56
x = 56/4
x = 14
therefore the amount of balls he puts into green bags is - 14 balls
Answer:
A and C
Step-by-step explanation:
There are

ways of selecting two of the six blocks at random. The probability that one of them contains an error is

So

has probability mass function

These are the only two cases since there is only one error known to exist in the code; any two blocks of code chosen at random must either contain the error or not.
The expected value of finding an error is then
measure of angle CED is 80
