Answer:
A
Explanation:
![\sf Probability\:of\:an\:event\:occurring = (Number\:of\:ways\:it\:can\:occur)/(Total\:number\:of\:possible\:outcomes)](https://img.qammunity.org/2023/formulas/mathematics/college/7eloctizz4bck4h5oqa5m8rmxi31of3oo0.png)
The spinner is evenly divided and numbered from 1 through 8.
![\sf \implies Probability\:of\:landing\:on\:any\:number= \frac18](https://img.qammunity.org/2023/formulas/mathematics/high-school/3dth76na1u98tnmdruakx6rm1mu5kxcbtm.png)
There are 4 even numbers (2, 4, 6 and 8)
![\sf \implies Probability\:of\:landing\:on\:an\:even\:number= \frac48=\frac12](https://img.qammunity.org/2023/formulas/mathematics/high-school/su0f0urn34rhelohstzuzy0w2t7bcbckn5.png)
There are 3 numbers less than 4 (1, 2 and 3)
![\sf \implies Probability\:of\:landing\:on\:a\:number\:less\:than\:4=\frac38](https://img.qammunity.org/2023/formulas/mathematics/high-school/hqz6a8jav227tj4s9crn4p8nybvh199vm8.png)
Therefore, the probability of landing of an even number and then on a number of less than 4 is:
![\sf \implies Probability=\frac12 * \frac38=(3)/(16)](https://img.qammunity.org/2023/formulas/mathematics/high-school/fq3ho89eyyaxrokmvojqteyj0v8zag05yn.png)
