Plz help I am very confused, brainliest goes to whoever answers correctly, and first

1/4 × 3 + 3/8 × 4 + 1/2 × 3 + 5/8 × 2

3/4 + 12/8 + 3/2 + 10/8

6+12+12+10/8

40/8

5

answer is 5 lb

All the kittens weigh 5 pounds altogether

Step-by-step explanation:

1/4 pounds: 3 kittens

3/8 pounds: 4 kittens

1/2 pounds: 3 kittens

5/8 pounds: 2 kittens

3*1/4 = 3/4

3/8*4 = 1.5

1/2*3 = 1.5

5/8*2 = 1.25

Sum up:

3/4 + 1.5 + 1.5 + 1.25 = 5

answer: c

step-by-step explanation: because you don't have to draw a point of intersection. couldyou give me brainliest?

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
