Answer:

6/23

Step-by-step explanation:

Probability is the number of possible outcome divided by the total number of outcomes. It is a ratio. Mathematically, the probability Pr of an event "a" happening given tat the total number of outcomes is T

Pr = a/T

Total number of students

= 11 + 12

= 23

The probability of picking a

Girl = 12/23

Boy = 11/23

The probability of picking a girl and  a boy (without replacement)

= 12/23 * 11/22

= 12/46

= 6/23

Paha777 [63]
Theres a formula to find the midpoint it’s... (x1+x2)/2, (y1+y2)/2. You fill in the x’s and y’s to get (-5+7)/2 for x, which equals 1 and (4-5)/2 to get -0.5. (1, -0.5) is your answer

Answer:

-1

Step-by-step explanation:
