Is a spinner is numbed from 1-10 which event has a theoretical probability of exactly 1/5? check all that apply. spinning a number less than 3 spinning a 4 or 5 spinning an odd number spinning a number greater than 8 spinning a number less than 8 asap

Step-by-step explanation:

Given that a spinner is numbered from 1-10.

Since all will have equal area, we find that probability of spinning one number is 1/10

Let us check one by one

i) Spinning a number less than 3, = spin in 1 or 2

=1/10+1/10 =1/5

ii) spinning a 4 or 5 has prob = 1/10+1/10=1/5

iii) Spinning an odd number =1/10*5=1/2

iv) spinning a number >8 = spin in 9 or 10

=1/10+1/10=1/5

v) spinning a number <8 = 7/10

Hence answers are

i, ii, iv

yes
