Question

A student randomly draws a card from a standard deck of 52 cards. He records the type of card drawn and places it back in the deck. This is repeated 20 times. The table below shows the frequency of each outcome.

Outcome Frequency
Heart 6
Spade 4
Club 7
Diamond 3


Determine the experimental probability of drawing a diamond.

Answer 1

The experimental probability of drawing a diamond is calculated by dividing the frequency of drawing a diamond by the total number of trials:

Experimental probability of drawing a diamond = Frequency of drawing a diamond / Total number of trials
Experimental probability of drawing a diamond = 3 / 20
Experimental probability of drawing a diamond = 0.15 or 15%

Therefore, the experimental probability of drawing a diamond is 15%.
