Answer:
0.1
Step-by-step explanation:
total number of marbles= 2+4+8=14 marbles
probability of getting 2blue
= 4/14×3/13= 4×3/14×13=12/182= 0.06593
to the nearest tenth= 0.1
3/6 is bigger because it simplifies to 1/2 and 3/8 is below 1/2.
Answer:
Time taken by the un powered raft to cover this distance is T = 192.12 hr
Step-by-step explanation:
Let speed of boat = u 
Speed of current = v 
Let distance between A & B = 100 km
Time taken in downstream = 32 hours


u + v = 3.125 ------ (1)
Time taken in upstream = 48 hours


u - v = 2.084 ------- (2)
By solving equation (1) & (2)
u = 2.6045 
v = 0.5205 
Now the time taken by the un powered raft to cover this distance

Because un powered raft travel with the speed of the current.

T = 192.12 hr
Therefore the time taken by the un powered raft to cover this distance is
T = 192.12 hr
