Liz flips a coin 40 times. The coin lands heads up 28 times and tails up 12 times. Complete each statement ​

(a)The theoretical probability of the coin landing heads up is___

(b)The experimental probability of the coin landing heads up is___

(c)The theoretical probability of the coin landing tails up is___

(b)The experimental probability of the coin landing tails up is___

(Type an integer or decimal)

Answer:

(a)0.5

(b)0.7

(c)0.5

(d)0.3

Explanation:

When a coin is tossed, there are two outcomes: Heads or Tails

(a)Theoretical Probability of the Coin landing Heads up =1/2=0.5

(b)In the experiment, out of a total of 40 trials, the coin lands heads up 28 times.

Experimental Probability of the Coin landing Heads up =28/40=0.7

(c)Theoretical Probability of the Coin landing Tails up =1/2=0.5

(d)In the experiment, out of a total of 40 trials, the coin lands tails up 12 times.

Experimental Probability of the Coin landing Tails up =12/40=0.3
