The answers are
a)111010 - 001111 = 101011 = 43
b) 000100 - 011000 = 111111111 (overflow) = -20
c) 010001 - 011010 = 11111111 (overflow) = -9
d) 010000 - 100100 = 1111111 (overflow) = -20
Step-by-step explanation:
a)111010 = 1×2⁵+1×2⁴+1×2³+0×2²+1×2¹+0×2⁰ = 32+16+8+0+2+0= 58
001111 = 0×2⁵+0×2⁴+1×2³+1×2²+1×2¹+1×2⁰ = 8+4+2+1=15
111010 - 001111 = 101011 = 43
b) 000100 = 0×2⁵+0×2⁴+0×2³+1×2²+0×2¹+0×2⁰ = 4
011000 = 0×2⁵+1×2⁴+1×2³+0×2²+0×2¹+0×2⁰ = 24
000100 - 011000 = 1111111111 (overflow), 4 - 24 =-20
c) 010001 = 1×2⁴+1×2⁰ = 17
011010 = 1×2⁴+1×2³+1×2¹ = 26
010001 - 011010 = 11111111 (overflow) 17-26=-9
d) 010000 = 1×2⁴ = 16
100100 = 1×2⁵+1×2² = 36
010000 - 100100 = 1111111 (overflow) 16-36=-20
25 times
From the question:
Number of :
Yellow = 2
Red = 3
Blue = 5
P(blue) = required outcome / Total possible outcomes = 5/ 10 = 1/2
If marble is drawn with replacement :
Number of times a blue marble is drawn from 50 trials :
P(blue marble) * 50
1/2 * 50
= 25 times
