Acoin is flipped 20 times. the results are 12 heads and 8 tails. the theoretical probability of getting heads is 60%.

true or false?

False

Step-by-step explanation:

Given experiment:

A coin is flipped 20 times.

The results are 12 heads and 8 tails.

Statement: The theoretical probability of getting heads is 60%.

To tell true or false.

Solution:

For the given experiment the results is 12 heads and 8 tails for a coin flipped 20 times.

The experimental probability of getting head can be given as:

⇒

⇒

⇒

while the theoretical probability of getting heads can be given as:

⇒ [Since probability getting heads on one flip is 0.5]

⇒

Thus, the statement is false.

✧･ﾟ: *✧･ﾟ:*    *:･ﾟ✧*:･ﾟ✧

✅  FALSE

✧･ﾟ: *✧･ﾟ:*  Explanation:  *:･ﾟ✧*:･ﾟ✧

❗ This is Experimental Probability:   12 Heads out of 20 Tosses.

12/20 reduces to  6/10, 0.60, and 60%.

The answer to this question is FALSE, because this is NOT Theoretical Probability.

26 is 33.33% of 78

step-by-step explanation:

26 is what percent of 78?

26 is p% of 78

equation: y = p% * x

solving our equation for p

p% = y/x

p% = 26/78

p = 0.3333

convert decimal to percent:

p% = 0.3333 * 100 = 33.33%
