Suppose you have rolled a six-sided die fifty times and recorded the result of each roll.

a_sh-v [17]

Using it's concept, it is found that the relative frequency probability of rolling an even number based on this experiment is $\frac{11}{25}$ .

A relative frequency is the <u>number of desired outcomes divided by the number of total outcomes</u>.

In this problem:

50 dices are thrown, hence $T = 50$ .
22 resulted in an even number, hence $D = 22$

The <u>relative frequency</u> is given by:

$f = \frac{D}{T} = \frac{22}{50} = \frac{11}{25}$

Mr. Clark claims that he has a coin that is weighted so that the probability of heads is 40%. To test this, his students flip th

Brrunno [24]

While I'm unsure what the word choices were, his claim is likely to be true.

Since he claims the probability of heads is 40%, that should be what we see in an experiment. 0.38 is very close to 0.40, or 40%, so this is true. Therefore his claim is likely to be true, and the probability of tails should be about 60%.
