Answer: For the first one, 12.5% chance
Step-by-step explanation:
The probability of flipping a coin and getting tails is 50%. Then, if you were to flip two coins and get both tails, you would have to divide the 50% by 2, which is equals to 25% of flipping two coins and getting them both tails.
So now we know...
Flipping one coin gives you 50% tails and 25% of flipping two coins and getting two tails
So now, we do it again with the third coin. We would divide the 25% by 2, which will get us to a 12.5% of getting all tails, or in fractions, 1/8
I’m not exactly sure about the other ones but I hope you found this one helpful!
Answer:
There are 25 chickens and 20 rabbits
Step-by-step explanation:
Let
x-----> the number of chickens
y ----> the number of rabbits
Remember that
1 chicken has two legs
1 rabbit has four legs
so
2x+4y=130 -------> equation A
x=y+5 -----> equation B
Substitute equation B in equation A and solve for y
2(y+5)+4y=130
2y+10+4y=130
6y=120
y=20 rabbits
Find the value of x
x=y+5
x=20+5=25 chickens
