Maths Question - Goals

[stho1978]

Need someone to confirm the following (it’s simple GCSE question and think I know but want someone to double check!!!!) If over 32 football matches the goal distribution is as follows: Total number of goals: Matches 0 goals 1 goal 2 goals 3 goals 4 goals over 5 goals 32 1 match 6 matches 8 matches 8 matches 3 matches 6 matches So in 1 match out of the 32 there were no goals scored, in 6 matches out of the 32 1 goal was scored, in 8 matches out of the 32 2 goals were scored etc. Therefore in % terms: 0 goals 1 goal 2 goal 3 goal 4 goal Over 5 goal 3.13% 18.75% 25% 25% 9.38% 18.75% What is the likely hood of a match having over 0 goals, over 1 goal etc? Now if there is a 25% chance of there being 3 goals exactly then there must be a 75% of there not being 3 goals. But I want to know what’s the likelihood of there being more than 3 goals. (I make it around 28.125%)

Re: Maths Question - Goals I've tried to edit this post, without success, so it reads like this (more spread out): Matches 0 goals 1 goal 2 goals 3 goals 4 goals over 5 goals 32 1 match 6 matches 8 matches 8 matches 3 matches 6 matches

Re: Maths Question - Goals Ahhhhh it's not working! Anyway, hope you get the general idea.

Re: Maths Question - Goals Quite straight-forward in Excel..... Probability of > 0 goals - (6+8+8+3+6)/32.... 96.9% Probability of > 1 goal - (8+8+3+6)/32.... 78.1% Probability of > 2 goals - (8+3+6)/32.... 53.1% Probability of > 3 goals - (3+6)/32.... 28.1% Probability of > 4 goals - (6)/32.... 18.8% But, of course, it's a very small sample :ok

Re: Maths Question - Goals Thank you very much. Just what I thought and a very simple question that most teenagers could answer but wanted to make sure I was right. I know it's a small sample but I just wanted to make sure my workings were correct.

Probably already in your thinking too, but that sample size is very small to be basing probabilities on, to a reliable degree.

Re: Maths Question - Goals Yeah I know but just checking my workings rather than the sample. I can use it on larger samples if needed. Thanks for the feedback though.
