Your vertex would be (3,4)
Using the probability concept, it is found that:
a) P(girl) = 1/3, which means that 1/3 = 33% of the time, the first batter will be a girl.
b) P(boy) = 2/3, which means that 2/3 = 67% of the time, the first batter will be a boy.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
In this problem, in a total of 15 people, 5 are girls and 10 are boys, hence:

Answer:
a)HCF between 774&252 is=18
LCM between 774&252=10836
b)HCF between 204&544 is=68
LCM between 204&544 is=1632
c)HCF between 770&385 is=385
LCM between 770&385 is =770
d)HCF between 477&552=3
LCM between 447&552 is =82248
Step-by-step explanation:
a)because LCM=2×2×3×3×7×43
b)because LCM=2×2×2×2×2×3×17
c)because LCM=2×5×7×11
d)because LCM=2×2×2×3×23×149
