Question

I have a very relaxing break playing Solitaire as often as I could. After playing 500 games, my success rate is 49%. How many games do I need to win to increase my success rate to 50%?

Answer 1

5 more games to be won for the 50% success rate.

Explanation:

Total number games played = 500

Number of successful games = 49% of 500

= 500 ×
`(49)/(100)`

= 245

Number of successful games for the success of 50% = 500 ×
`(50)/(100)`

= 250

Therefore, number of game you have to win more = 250 - 245

= 5 games
