Step-by-step explanation:
there are 50 students and 5 prizes (1 + 1 + 3).
so, already in natural language we would say "there is 1 prize for every 10 students".
formally, remember the rule of probability : desired outcomes over total possible outcomes.
this is here
5/50 = 1/10 = 0.1
your can see it also this way :
if there was only 1 prize, each student would have a chance of 1/50 of winning.
now there are 5 prizes, which gives everybody 5 times the chance of winning. which is then 5×1/50 = 5/50 = 0.1
Answer: 2.82
Step-by-step explanation:
Answer:
She needs to put the meal in the oven on or before 6:55pm.
Step-by-step explanation:
It is given that Jasmine wants to eat at 8:00pm.
The time she needs to cook her meal = 65 mins.
To find the time she needs to put the meal in the oven, we have to subtract 65 mins from 8:00pm
65 mins = 1 hour and 5 mins.
So, 1 hour before 8:00pm is 7:00pm.
5 mins before 7:00pm is 6:55pm.
Hence, she needs to put the meal in the oven on or before 6:55pm so that she can't miss 800pm to eat.
