Lisa flipped a coin 50 times and got a head 20 times. What was the experimental probability of flipping a heads? what is the theoretical probability of flipping a heads?

2/5 (or 0.4)

Step-by-step explanation:

There was 50 flips, that's the total. #/50

Head was 20 times, that's the answer we're looking for. 20/50

20/50 Simplified is 2/5 (or 0.4)

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2
