If we randomly pick two persons from the population, each one will have a probability of 1-1/28=27/28 of being a non-carrier.
Thus for neither to be non-carrier, the probability is the product of the individual probabilities since the picks are assumed independent (with a large enough population).
Probability = (27/28)*(27/28) = 729/784
or approximately 0.930
Parallelogram.
Opposite sides are parallel.
in a rhombus and square all sides are equal so it isn't those.
It isn't a rectangle either because in a rectangle all angles are ninety degrees
2πr= c
So π=3.14
56÷2= 28
2 x 3.14 x 28=c
87.12 x 2 = 174.24
The circumference is 174.24
Answer:
A i think its a A try. it it that looks correct
A. 15 × 1 1/2= 15/1 × 3/2= 45/2= 2 2/5
b.15min +1extra minute=16min. × 15 students =240min so no not enough time
