You have 10 tries. you got heads 6 times. the probability is 6/10. if you put this fraction into your calculator, or you divide 6 and 10, you’ll get .6 or .60. changing it into a percent would be 60 percent. Just check what your assignment calls for. if it says a fraction or proportion then use 6/10. if it wants a percentage use 60%.
I got 2.6 I hope that's right
For all of these answers, the equation used was (AB + CD)/2 = EF
1.12+24=36 36/2=18
2. 21 + 35 = 56 56/2 = 28
3. (7 + EF)/2 = 9
multiply by 2
7 + EF = 18
subtract 7
EF = 11
4. (AB + 32)/2 = 22
Multiply by 2
AB + 32 = 44
Subract 32
AB = 12
5. Average
to be honest I agree that would be 6s
