Answer:
U = -3
Step-by-step explanation:
U/-1 +-4=-1
Add 4 to each side
U/-1 +-4+4=-1+4
U / -1 = 3
Multiply each side by -1
U / -1 * -1 = 3* -1
U = -3
Answer:
The probability is 1/9
Step-by-step explanation:
The probability of rolling a 5 the first time is 1/6
The probability of rolling a number greater than 2
Numbers greater than 2 are 3, 4, 5, 6
So the probability of rolling a number out of these four is 4/6
So the probability of rolling a five for the first time and the probability of rolling a number greater than 2 the second time will be
1/6 * 4/6 = 4/36 = 1/9
