Answer 1

Answer:

13/7

Step-by-step explanation:

Answer 2

Total number of marbles in the box =5+8+4=17

↘️ɪ) P(ʀᴇᴅ) = ɴᴏ. ᴏғ ʀᴇᴅ ᴍᴀʀʙʟᴇs/ᴛᴏᴛᴀʟ ɴᴜᴍʙᴇʀ ᴏғ ᴍᴀʀʙʟᴇs

P(ʀᴇᴅ) =5/17

↘️ɪɪ) P(ᴡʜɪᴛᴇ) = ɴᴏ. ᴏғ ᴡʜɪᴛᴇ ᴍᴀʀʙʟᴇs/ᴛᴏᴛᴀʟ ɴᴜᴍʙᴇʀ ᴏғ ᴍᴀʀʙʟᴇs

P(ᴡʜɪᴛᴇ) =8/17

↘️ɪɪɪ) P(ɢʀᴇᴇɴ) = ɴᴏ. ᴏғ ɢʀᴇᴇɴ ᴍᴀʀʙʟᴇs/ᴛᴏᴛᴀʟ ɴᴜᴍʙᴇʀ ᴏғ ᴍᴀʀʙʟᴇs

P(ɢʀᴇᴇɴ) =4/17

➡️P(ɴᴏᴛ ɢʀᴇᴇɴ) =1− P(ɢʀᴇᴇɴ) =13/17
