Answer:
0.5
Step-by-step explanation:
The probability that the first mouse turns left and the second mouse turns right is 0.5 × 0.5 = 0.25.
The probability that the first mouse turns right and the second mouse turns left is 0.5 × 0.5 = 0.25.
So the probability that only one mouse turns left is:
P = 0.25 + 0.25
P = 0.5
Another way of looking at it: the probability that only one mouse turns left is 1 minus the probability that both turn left or both turn right.
P = 1 − (P(both left) + P(both right))
P = 1 − (0.5 × 0.5 + 0.5 × 0.5)
P = 0.5
Case 1: You have an Ace and a seven.
There are 4 ways to pick 1 Ace out of 4. There are 4 ways to pick 1 seven out of 4. -----> 4*4 = 16
There are 16 ways to be dealt an Ace and a seven.
Case 2: You have a two and a six.
In the same way there are 4*4=16 ways to be dealt a two and a six.
Case 3: You have a three and a five.
In the same way there are 4*4=16 ways to be dealt a three and a five.
Case 4: You have 2 fours.
There are 6 ways to get 2 fours out of 4. (4 choose 2)
Total number of outcomes = 16+16+16+6 = 54
