First term, a, is 2. Next term, -2, is the product of 2 and -1 and is -2. Next term, 2, is the product of -2 and -1. Thus, the first term, a, is 2 and the common ratio, r, is -1.
Answer:
Step-by-step explanation:
In order to solve this, you would need to multiply the probability of you choosing the one that goes first, so 1 in 16 discs, then the next one so 1 in 15, and so on untill the fifth disc.
So you would have to do this:
That is the probability that the rack ends up in alphabetical order, if you pull discs randomly, 1 in 524160 chances.
Y ≤ -3x - 23 is your answer.
Answer:
1). 0.1667
2). 0.3333
3). 0.3333
Step-by-step explanation:
1). Probability that the student was female and got a 'B'
=
=
= 0.1667
2). Probability that the student was male and got an 'A'
=
=
=
= 0.3333
3). Probability that the student got a B =
=
=
= 0.3333
