Answer: (0,-5)(1,-6) is the answers
The answer is 2
Look at the picture attached for steps
Each question is either true or false, so the sample space is 2, true and false, two states only.
what's the probability she got one correct, well, the favorable outcomes is 1, possible outcomes is 2, so 1/2.
what's the probability that she got all four correct, we simply multiply the probability of each,
It's (5,7). This is a translation. (x-4) means moving the x coordinate to the left 4 times. If it was positive it would move to the right. (y+15) moves the y coordinate to the right 15 times also would move to the left if negative.
