You maybe surprised what the outcome of your bet will be and your support for the betting site believing that the probability of the Egyptians progressing to the final is slime may turn out in a different way if care is not taking. If the gambling site will provide you the accurate something and it turned out that way how will they make profit. I believe the Egyptians will progress to the final.
The chance for Egypt progressing to the final is not so slim. Here are the current odds for the cup winners:
Senegal 2.5
Cameroon 3.0
Egypt 4.0
Burkina Faso 11.0
Burkina Faso is clearly the outsider in this group. Cameroon is favored against Egypt, but not by that much. Egypt already has shown that they can win against stronger teams and they already faced 3 teams that were stronger on the paper (1 loss against Nigeria, 1 draw against Ivory Coast and 1 win in extension time against Morocco). They are now a typical "tournament team" and seem to be comfortable in their role as outsiders. Cameroon of the other hand has not faced a stronger team yet and might fail just like Ivory Coast or Morocco.
