Answer:
The probability is 1/8 or 0.125
Step-by-step explanation:
In this question, we are concerned with calculating the probability that when a coin is flipped there would be a show of heads three times.
In flipping of a coin, there are only two possible results with equal probability. The probability of both events i.e P(H) and P(T) is equal and that is 1/2
Thus the probability of getting heads three times in a row will be P(HHH) meaning P(H) and another P(H) and another P(H)
When we have and in a probability question, that means we are to multiply the probabilities together.
Hence, P(HHH) = 1/2 * 1/2 * 1/2 = 1/8
Answer:
$0.3
Step-by-step explanation:
8.90x2=17.8
1.75x2=3.5
17.8+3.5=21.3
21.90-21.3=0.6
0.6/2=0.3
462809 round off to 500000.
256738 round off to 300000.
500000+300000=800000
Answer:
52% are girls
Step-by-step explanation:
We know that there are 650 sixth-graders and 338 of them are girls, we are then asked to find the percentage of how many are girls.
We have the fraction 338 over 650 but need to reduce it.
To solve this, we need to find the GCF of 650 and 338, which is 26, so divide both the numerator and denominator by 26.
Now divide the 13 and 25 :
13 / 25 = 0.52
0.52 * 100 = 52%
Therefore, 52% of the sixth-graders in the school are girls
