Your friend decides to flip a coin repeatedly to analyze whether the probability of a head on each flip is one half 1 2. He flips the coin 1010 times and observes a head 66 times. He concludes that the probability of a head for this coin is six tenths 6 10 equals

0.6

Step-by-step explanation:

Outcome of heads =66

Total number of times that coin was flipped=1010

Probaibility P (heads)= 66/1010 =0.6

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
