Step-by-step explanation:
1 m = 4 cm
therefore,
A = 2.5 m = 2.5×1 m = 2.5×4 cm = 10 cm
B = 2.75 m = 2.75×1 m = 2.75×4 cm = 11 cm
D = 3.75 m = 3.75×1 m = 3.75×4 cm = 15 cm
The theoretical probability of getting two tails on two coin tosses is 0.25.
<h3>How to calculate the probability?</h3>
The theoretical probability is the ratio of the number of favorable outcomes to the number of possible outcomes. Given a coin is tossed twice.
We have to find the theoretical probability of tossing two tails. The probability of getting tails on the toss of a coin is 1/2 0r 0.5.
Therefore, the probability of getting two tails on two coin tosses is 0.5 × 0.5 or 0.25.
The theoretical probability that a coin toss results in two heads showing is 0.25.
