There are 25 remaining slots on a field trip. the students are chosen at random to go. if there are 16 boys in your class and 9 girls, what is the probability a girl is chosen first?

9/16

Step-by-step explanation:

You put the girls at the top and boys at the bottom and therefore you wwill get your probability.

The one you put on top is how you can find your probability.

(sorry it's hard to explain)

my discord name is kinglilcliff12#7776

she played for 18.75 hours.

step-by-step explanation:

if she played 2/4 of a hour on tuesday. and there is 60 minutes in an hour and 60 divided by 4 is 7.5. and she played 2/4 of an hour on thursday then again 60 divided by 4 is 7.5, you add 7.5+7.5=56.25. now you have to do 1/4 of an hour, it equals 3.75. now you have to add them all up. 3.75+7.5+7.5=18.75

i hope this and i hope you get it right. it took me a while to get this done for you. : )
