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

Answer:

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

Step-by-step explanation:

Total number games played = 500

Number of successful games = 49% of 500

                                                 = 500 × $\frac{49}{100}$

                                                 = 245

Number of successful games for the success of 50% = 500 × $\frac{50}{100}$

                                                                                        = 250

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

                                                                                    = 5 games
