42.8% players practised more than one time a week

Step-by-step explanation:

Total no of players practising = 7

Players who practice more than once a week= 3

(According to graph player no 1,3 and 5 played more than once in a week)

To find the percentage of the players who practised more than one time a week

The formula used is:

percentage of players practising more than one time a week=  ( no of player playing more than once / total no of players ) x 100%

Putting values in the formula

percentage of players playing more than one time a week= 3/7x100%%

                                                                                       = 0.428x100%%

                                                                                       = 42.8%

So, 42.8% players practised more than one time a week
