Probability of Spin Resulting in Even # or <4

Click For Summary
SUMMARY

The probability of spinning an even number or a number less than 4 on a standard spinner is definitively calculated as 3/4 or 6/8. This conclusion is reached by applying the union set operation to the outcomes of 4/8 (1/2) and 3/8. The calculated probability of 3/4 is not included in the provided answer choices A-D, indicating a potential oversight in the options given.

I tried to answer it and got 3/4 or 6/8 after using the union set operation for 4/8 or 1/2 and 3/8, based on what is being asked in the problem. https://www.mathplanet.com/education...lity-of-eventshttps://uploads.tapatalk-cdn.com/20180329/39d5da5505f3c8ccaa27619bfbfd516c.jpghttps://uploads.tapatalk-cdn.com/20180329/3cd8ecb6e781e932cdcc6cdba59ea7b5.jpg

Hi MIIF, and welcome to MHB!

I agree with you. The answer should be 3/4, which is not listed among the choices A.-D.
