The answer is 0.24
To calculate this, a multiplication rule is used. The multiplication rule calculates the probability that both of two events will occur. In this method, the probabilities of each event are multiplied. Here we have two events:
1. The probability that the pianist will be a boy,
2. The probability that the alternate will be a girl.
So, let's calculate these probabilities:
There are in total 5 children:
2 boys + 3 girls = 5 children.
1. The probability that the pianist will be a boy is 2 boys out of 5 children, which is 2/5.
2. The probability that the alternate will be a girl is 3 girls out of 5 children, which is 3/5.
<span>The probability that the pianist will be a boy and the alternate will be a girl is:</span>
<span>2/5 </span><span>× 3/5 = 6/25</span>
<span>6/25 </span><span>× 4/4 = 24/100 = 0.24</span>
estimate value of :- 2.99548 is 3
estimate value of :- 1.8342 is 2
So 3•2=6
so 6 is your answer
Answer:
3 1/3 cups of flour
Step-by-step explanation:
20/4 = 5
20 servings is 5 times 4 servings, so you need 5 times the amount of ingredients.
5 * 2/3 = 10/3 = 3 1/3
Answer: 3 1/3 cups of flour
Wait is it not at all 14.5 or 14 1/2 Because with the math I did I got 14 1/2
Answer:
x = 5m/s
Step-by-step explanation:
Distance flying out = 12 km (headwind)
Distance flying back = 12 km (tailwind)
total distance = 12 + 12 =24 km
wind speed = 1km/h
speed going out (with headwind) = (x - 1) km/h
speed coming back (with tailwind) = (x + 1) km/h
Time taken to go out = distance going out / speed going out
= 12 / (x-1)
Time taken to come back = distance coming back / speed coming back
= 12 / (x+1)
total time = time taken to go out + time taken to come back
5 =[ 12/(x-1) ] + [ 12/(x-1)]
expanding this, we will get
5x² - 24x - 5 = 0
solving quadratic equation, we will get
x = -1/5 (impossible because speed cannot be negative)
or
x = 5 (answer)
