Rob flips a coin 12 times. the result of each flip is heads up or tails up. the size of the sample is 4096. the number of outcomes that result in exactly 3 heads is 220. how many outcomes result in more or less than 3 heads?

hi,

i'm 75% sure the answer is 1,1 to both lines.

have a great day

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
