Answer: 3/8
Step-by-step explanation:
Since it is a fair coin, then generally, P(Head) = P(Tail) = ½
And since we've been asked to find the probability that the number of heads in the first two tosses be equal to the number of heads in the second two tosses, tossing a fair coin four times, the possible outcomes of having equal number of heads in first two tosses and second two tosses becomes:
[HHHH] or [HTHT] or [THTH] or [TTTT] or [HTTH] or [THHT]
=[½*½×½*½] + [½*½×½*½] + [½*½×½*½] + [½*½×½*½] + [½*½×½*½] + [½*½×½*½]
=1/16 * 6
=6/16
=3/8.
are those the options? something is wrong here and I'm not sure what. I'm sorry if this is wrong, I tried my best
Answer:
-2,928
Step-by-step explanation:
12 ( 32 - [ 23 • 12 ] )
order of operations PEMDAS ( parenthesis, exponents, multiplication/division, addition/subtraction )
23 • 12 = 276
12 ( 32 - 276 )
12 ( -244 )
-2,928
1) (2i-4)-(6i+9) = 2i-4-6i-9 = -4i-13
2) (-3+8i)+(3-8i) = -3+8i+3-8i = 0+0i = 0
