1500. since hes marking it up by 50% then take half of 3000 to get your answer
55 minus 18 is 37 and then it would be 37,000 and then you just convert it so it is 37% of 100 (the answer is 37%)
Answer: 15 / 56
Step-by-step explanation:
Number of red checkers = 3
Number of black checkers = 5
Total number of checkers = 8
P(black, then red) = 5/8 × 3/7 = 15/56
We should note that the probability to pick a black checker first will be 5 out of 8. Then, there'll be 7 checkers left and the probability to pick a res checker will be 3/7. We then multiply the probabality of each together.
