Answer:
Answer choice C
Step-by-step explanation:
Similarly to the previous problem, there are two possibilities. In the first possibility, the chance of picking a digit lower than 7 is 6/9 or 2/3, because there are 6 digits below 7 and 9 digits in total. In this scenario, the probability of the second digit being below 7 is 5/8, since one of the digits has already been taken. The probability here is 5/8*6/9=5/12. In the other scenario, the probability of picking a number higher than 7 is 3/9 or 1/3. In this scenario, the probability of picking below 7 for the second digit is 6/8 or 3/4, because one of the digits has not been taken. 3/9*6/8= 1/4. Adding these two together, you get 8/12=2/3, or answer choice C. Hope this helps!
Answer:
7
Step-by-step explanation:
n= 4, a= -5, d = -1-(-5)= -1+5 = 4
Tn = a + (n-1)d
Tn = -5 + (4-1)4 = -5 + (3)4 = -5+12 = 7
