10 cards are numbered from 1 to 10 and placed in a box. One card isselected at random and is not replaced. Another card is then randomlyselected. What is the probability of selecting two numbers that are less than62

A:
Answer:0.889Step-by-step explanation:I think it is multiplied.10 *9 = 90which is the total number of ways you can draw 2 cards without replacement.I think it is easier to figure out how many possibilities there are over 62 and go from there.10*910*810*7===========9*8 9*7So there are 5 combinations that are over 62. There are 5 more possibilities because you could draw them in the reverse order9 * 108 * 107 * 10 8* 97 * 9 In all there are 10 ways of drawing numbers that are over 62So what is the probability of drawing 2 cards above 62?10/90 = 1/9 = 0.111Therefore, there must be a probability of 1 - 0.111 for under 62 = 0.889
