4. George flips a colored chip that is red on one side and black on the other a total of 20 times. What is the probability of the 21th flip resulting in landing on the black side up?

Vocaloid:
keep in mind the first 20 flips have no effect on the 21st flip for a two-sided coin (one red one black) what would be the probability of landing on black?
jonathan5654:
im confused
Vocaloid:
there are two total outcomes (red and black) so the probability of black is just 1/2
jonathan5654:
is that the answer??
Vocaloid:
yes
