answer:step-by-step explanation:here, the total dishes = 10dishes having meat = 3 ( chicken, meatloaf and hamburger )thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes=therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes===⇒ option b is correct.Reply

3/8 project per hour
Step-by-step explanation:
Take the part of the project done and divide by the time
3/10 project ÷ 4/5 hours

3/8 project per hour
3/8
Step-by-step explanation:
3/10 div 4/5
Divide 3/10=0.3 by 4/5=0.8 by multiplying 3/10=0.3 by the reciprocal of 4/5=0.8.
3/10x(5/4)
Multiply 3/10 =0.3 times 5/4 =1.25 by multiplying numerator times numerator and denominator times denominator.
3x5/10x4
Do the multiplications in the fraction 3×5/10x4
15/40 = 0.375
Reduce the fraction 15/40 = 3/8 =0.375 to lowest terms by extracting and canceling out 5.
3/8
answer:
step-by-step explanation:
here, the total dishes = 10
dishes having meat = 3 ( chicken, meatloaf and hamburger )
thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes
=
therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes
=
=
=
⇒ option b is correct.
